MILTON B. ROLLER, OF PALO ALTO, CALIFORNIA, ASSIGNOR TO THOMAS DAY COMPANY, OF SAN FRANCISCO, CALIFORNIA, A CORPORATION OF CALIFORNIA.

LIGHTING-FIXTURE.

Specification of Letters Patent.

Patented July 23, 1918.

Application filed March 19, 1918. Serial No. 223,458.

To all whom it may concem:

Be it known that I, MILTON B. ROLLER, a citizen of the United States, residing at Palo Alto, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Lighting- Fixtures, of which the following is a specification.

My invention relates to that class of lighting-fixtures comprising a bowl, a canopy, and a lamp within the bowl.

My invention consists in the novel means, hereinafter fully described, for assembling these parts and suspending them from the ceiling.

The object of the invention is to simplify and improve the construction and to render easy the assemblage of the parts of a'fixture of this type.

Referring to the accompanying draw- 1ngs- Figure 1 is a vertical section of my improved lighting-fixture.

Fig. 2 is a part section and part side elevation, enlarged, of the holder-ring.

Fig. 3 is a plan of the same.

1 is the bowl, 2 is the canopy and 318 the lamp. 4: is the lamp-socket and 5 are the outlet wires, here shown broken but which pass in practice to the junction box 6 in the ceiling 7. 8 is the strap of the junction box secured thereto by the nipple 9 and nut 10. 11 is the holder-ring. It is formed with a horizontal inwardly extending top flange 11, a first step 11*, below the top, a second step 11, below the first step, and a vertical foot flange 11 which preferably terminates in a bead 11. The bowl 1 enters and is suspended from the foot-flange 11 of the holderring being held by the clamping-screws 12. The canopy 2 is supported on the second step 11 of the holder-ring. The lamp- .socket 4 is engaged peripherally by the top flange 11 of the holder-ring and is supported thereby; and finally the holder-ring is itself suspended from the strap 8 of the junction-box by means of hanger rods or wires 13, threaded at their upper ends in the strap, and at their lower ends passing through the first step 11 of said ring, and receiving nuts 14 below.

As shown in Fig. 3, the step 11 of the holder ring may have several vent holes 15 in it, in addition to the hanger-rod holes.

In this construotion and arrangement, it will be seen, the holder ring suspends the bowl, supports the canopy, carries the lampsocket, and is itself suspended from the junction box strap.

I claim In a lighting-fixture, and in combination with its bowl, canopy and-lamp-socket, a holder-ring formed with a top flange on which .the lamp-socket rests and is supported, a first step, a succeeding second step on which the canopy is supported, and a foot-flange by which the bowl is suspended, and hanger rods engaging the holder ring through its first step and suspending it from the ceiling.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
